Compound Hot‐Dry Days (CHDDs) and Their Implications on Maize Yields in the Free State Province, South Africa

open access: yesInternational Journal of Climatology, EarlyView.
Compound hot‐dry events occurring during the maize growing period are increasing significantly (p < 0.05) with time, with the median values ranging from 93 to 120 days. El Niño Southern Oscillation (ENSO) influences the variability of compound hot‐dry events with high significance (p < 0.05) positive Pearson correlation.

A review of remote sensing applications in flower phenology detection

open access: yesJournal of Ecology and Environment
The shift in flowering phenology with plants blooming earlier due to climate change, disrupts the synchronization between plants and pollinators by creating temporal and spatial mismatches.

Growing Degree‐Day Trends Associated With ‘False Springs’ in the Continental United States

open access: yesInternational Journal of Climatology, EarlyView.
Earlier spring warming has increased growing degree‐day (GDD) accumulation prior to the last freeze at some US locations (red circles = stat. sig. increases). However, after accounting for spatial autocorrelation using a false discovery rate approach, few trends remain significant, indicating no coherent continental‐scale increase in false spring risk.

Phenological Gardens Protocol [PDF]

open access: yes, 2003
The purpose of this resource is to observe the flowering and leaf stages of selected garden plants throughout the year. After a phenological garden is planted, students observe the growth of leaves and blooming of flowers on the plants. These plants were

Influence of genetic diversity, drought stress and rhizobial symbiosis on the nutritional quality of common vetch (Vicia sativa L.) grain

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Legumes are the primary source of plant protein in both human and livestock diets and, therefore, play an essential role in nutrition. Common vetch (Vicia sativa L.) is a grain legume widely used in animal feed. Its nutritional properties, particularly its high protein content, make it an adequate component to enrich feedstuffs ...

Flowering and Climate Change

open access: yesSibbaldia, 2007
Analysis of data from other studies of flowering and leafing phenology suggests that temperature and photoperiod can influence first-flowering date at up to nine developmental stages prior to flowering.

Reproductive phenology and its drivers in a tropical rainforest national park in China: Implications for Hainan gibbon (Nomascus hainanus) conservation

open access: yesGlobal Ecology and Conservation, 2020
Reproductive plant phenology, such as the seasonal timing of flowering or fruiting, influences many aspects of tropical forest communities, but there are few studies examining potential drivers of phenological patterns, especially in south China.
